Sorry no real hint - just be careful with the additional memory and CPU resources spent by the video stream.

I know our R&D had to tweak and adjust ABB's own solution - VideONet Connect for 800xA quite a bit before it became useable.

The memory budget in 32-bit Windows does not leave too much headroom in the workplace process - I sincerely recommend using 64-bit version of Windows 7 for clients that shall have live video and to avoid using it in thin clients or remote desktop based workplaces (RDP does not allow any kind of hardware acceleration; all code need to run on the terminal server cores).

Below a link that will work on ABB Intranet (or search for 2PAA109407-510 on SolutionsBank):

Thank you Stefan for your reply. The solution for video streaming was chosen before ABB's VideONet appeared. Moxa VPort works well but I can't make it run in graphic display or just as an ActiveX Wrapper Aspect standalone. I've searched through 3BSE049230-510_E_en_System_800xA_Engineering_5.1_Process_Graphics and found the functionality called "Item Hosted Input Items". I'm not sure if it can be used for ActiveX Wrapper primitive. If so, mayby I can provide parameters for VPort?
